Abstract: A navigable craft that includes a fuselage with a tiltable section positioned behind a non-tiltable section opposite to a nose. A set of wing assemblies connected to the non-tiltable section of the fuselage. Each wing assembly includes an airfoil connected to the non-tiltable section of the fuselage at a first cross-sectional end of the airfoil and a non-tiltable propulsion generator connected to a second cross-sectional end of the airfoil opposite to the first cross-sectional end of the airfoil. The propulsion generator extends parallel and adjacent to the non-tiltable section of the fuselage, and one or more stabilizers connected to at least one of the non-tiltable propulsion generator, the airfoil, and the fuselage. The landing assembly is connected to the propulsion generator or the airfoil. The landing assembly is aligned aerodynamically with the second cross-sectional end and extends in a direction adjacent to the tiltable section of the fuselage.

Abstract: An apparatus in some implementations includes a metalens, an image sensor, and an actuator. The metalens is con-figured to generate multiple diffractive orders of an image at respective corresponding focal lengths. The actuator is operable to move at least one of the metalens or the image sensor to each of multiple positions so that a distance between the metalens and the image sensor is adjustable. The distance between the metalens and the image sensor for each respective one of the positions corresponds to a particular one of the focal lengths.

Abstract: A lifter for windshield wiper blade includes a body having first and second opposite end portions. The body is horizontally elongate with a vertically low profile. The first and second end opposite portions are without any corners. The first opposite end portion releasably contacts the windshield when the body portion is positioned between a wiper arm and a windshield. The second opposite end portion releasably supports the wiper arm in a spaced apart relationship to the windshield when the first opposite end portion contacts the windshield and the body portion is positioned between the wiper arm and the windshield. The first and second end opposite portions are free from attachment to the wiper arm and the windshield, The body is supportively firm along the vertically low profile and vertically flexible along the second opposite end portion in supporting the wiper arm. The body has a positive water buoyancy.

A substantially flexible material is disposed on at least the outer surface of the gripping portion of the connector body. An intravenous line is coupled to the distal end of the connector body. A luer connector fitting is disposed on the proximal end of the body, the luer connector having an outer diameter less than a maximum exterior thickness of the gripping portion of the connector body.

Abstract: A system for and method of detecting and correcting incomplete data associated with a project is provided. The system includes a graphic module for creating a graphic output. The graphic output includes a plurality of inter-connected nodes, each node representing a party and each connection representing a relationship between the parties. The first node represents a property owner. In this way, the graphic output provides a visual indication of incomplete data if one or more node is not connected, directly or indirectly, to the first node. The system further includes a table module for creating one or more output table. The output table includes first and second groups of cells representing parties, the first and second groups of cells being positioned relative to each other so as to represent a relationship between the parties. The output table provides a visual indication if data is incomplete.

Abstract: A well tool adapted to be connected with and disconnected from a well tubing using a power tong device having a pair of tongs, a gripping span between the pair of tongs, and a maximum clearance diameter for an object passing through the tongs. The well tool includes a tubular mandrel. The tubular mandrel has a maximum mandrel diameter which is no greater than the maximum clearance diameter. The tubular mandrel includes a first mandrel connector which is adapted for connecting the tubular mandrel with a first well tubing in order to provide a first connection. The tubular mandrel is configured so that when the power tong device grips a tong gripping surface on the tubular mandrel and the first well tubing in order to connect the tubular mandrel and the first well tubing, the first connection is located within the gripping span.

Abstract: A hybrid power source includes an electric power source, a first hydraulic pump powered by the electric power source, a hydrocarbon burning power source, and a second hydraulic pump powered by the hydrocarbon burning power source. A hydraulic fluid output is fed by a combined output from the first hydraulic pump and the second hydraulic pump. A controller is provided for dynamically calculating hydraulic fluid requirements at the hydraulic fluid output as work is performed. The hydraulic fluid requirements are primarily provided by the first hydraulic pump powered by the electric power source and supplemented, as directed by the controller, by the second hydraulic pump powered by the hydrocarbon burning power source.

Abstract: A method of protecting a top drive drilling assembly includes incorporating a shock absorbing sub incorporated in the top drive drilling assembly. The shock absorbing sub comprises a first body and a second body capable of relative axial movement, with a shock absorbing medium disposed between the first body and the second body to absorb any reactive axial force exerted upon the top drive drilling assembly.

Abstract: Systems, devices and methods for treating internal tissue defects, such as septal defects, are provided. An exemplary method of treating an internal tissue defect, specifically a method of closing a patent foramen ovale (PFO), can include passing a closure element from a right atrium through a septal wall in a first location and into the left atrium. A capture device, which can be configured as a snare-like device, can be used to capture the closure element in the left atrium and pull the closure element back through the septal wall in a different, second location, such that the closure element is routed over the PFO. The closure element can then be anchored and/or locked against the septal wall such that the PFO is at least partially closed.

Abstract: Systems and methods for treating internal tissue defects, such as septal defects, with clip-based devices are provided.
